CLICK TO SCAN
A 3D-printed lumbar disc herniation model, combining soft and hard materials, accurately replicates real patient data, including normal anatomical structures and various pathological conditions. It serves as a reference for surgical planning and doctor-patient communication.
The lumbar disc herniation model is a 3D-printed representation that combines soft and hard materials. The shape and severity of the lumbar disc herniation are derived from real patient pathological data and are formed through data fusion. This model includes the normal anatomical structures of the lumbosacral region as well as various lumbar disc herniation symptom models.
The normal anatomical model primarily includes the lumbar spine, sacrum, intervertebral discs, ligaments, spinal nerves, spinal dura mater, cauda equina, and other related structures. The pathological model integrates the morphological characteristics of central, lateral, and paracentral herniations. This model serves as a reference for the planning and design of intervertebral disc herniation surgery and as a teaching aid for doctor-patient communication.
Data Source: Data is selected from a high-precision digital human dataset, which includes original sectional data, refined segmentation data, and a three-dimensional geometric model of organ structures. This dataset encompasses anatomical structures such as bones, muscles, blood vessels, nerves, and ligaments. The voxel size of the dataset is 0.0384 mm × 0.0384 mm × 0.1 mm. Additionally, cadaveric specimens preserved in formalin are used as a reference and comparison basis for the 3D printing model.
Model Making: Voxels from the volume data on the surface of each anatomical structure are extracted from the original sectional dataset. A texture map of the geometric model is then generated to ensure that the appearance of each anatomical structure closely resembles that of real anatomical specimens.
